rlocus (MathScript RT Module Function)
Owning Class: dynchar
Requires: Control Design and Simulation Module and MathScript RT Module
Syntax
rlocus(SysInSISO)
[roots, gains] = rlocus(SysInSISO)
Description
Creates an Evans, or root-locus, plot of closed-loop poles of a single-input single-output (SISO) system model as the feedback gain increases from zero to infinity.
Inputs
| Name | Description |
|---|---|
| SysInSISO | Specifies a linear time-invariant (LTI) SISO model in transfer function, zero-pole-gain, or state-space form. |
Outputs
| Name | Description |
|---|---|
| roots | Returns the locations of the closed-loop roots of the SysIn model. roots is a complex matrix. |
| gains | Returns the gain values this function uses to create the root locus plot. gains is a real vector. |
Details
The following table lists the support characteristics of this function.
| Supported in the LabVIEW Run-Time Engine | Yes (if you request output) |
| Supported on RT targets | Yes (if you request output) |
| Suitable for bounded execution times on RT | Not characterized |
Examples
num = [1]
den = [1, 5, 6]
SysInSISO = tf(num, den)
